1. The mole ratio of H2SO4 and H2O in the equation = 3:3

2. The mole ratio of Mg and Mn in the equation = 3:2

Given

Reaction

1. Fe2O3 + H2SO4 → Fe2(SO4)3 + H2O

2. Mg + Mn2O3 → MgO + Mn.

Required

Balanced equation

Solution

1. Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O

aFe₂O₃ + bH₂SO₄ → Fe₂(SO₄)₃ + cH₂O

Fe, left = 2a, right=2⇒2a=2⇒a=1

S, left=b, right=3⇒b=3

H, left = 2b, right = 2c⇒2b=2c⇒2.3=2c⇒c=3

The equation becomes :

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

2. Mg + Mn₂O₃ → MgO + Mn.

aMg + Mn₂O₃ → bMgO + cMn.

Mn, left=2, right=c⇒c=2

O₂, left=3, right=b⇒b=3

Mg, left = a, right=b⇒a=b⇒a=3

The equation becomes :

3Mg + Mn₂O₃ → 3MgO + 2Mn.

Answer:

Fluorite

What is Fluorite? Fluorite is an important industrial mineral composed of calcium and fluorine (CaF2). It is used in a wide variety of chemical, metallurgical, and ceramic processes

Answer:

Follows are the solution to the given points:

Explanation:

Answer:

B) 1.183

Explanation:

To convert from grams (mass) to moles, we need to divide by the atomic mass (amu)..

The amu of [tex]CO_{2}[/tex]  is 44.008

52.06/44.08 = 1.182966733

This can be rounded to 1.1830 moles of CO2

1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.

Explanation:

Given :

The 52.06 grams of carbon dioxide.

To find :

The moles of carbon dioxide.

Solution:

The mass of carbon dioxide = 52.06 g

The molar mass of carbon dioxide = 44.01 g/mol

The moles of carbon dioxide:

[tex]=\frac{52.06 g}{44.01 g/mol}=1.183 mol[/tex]

1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.

Answer:

15.12g

Explanation:

Given parameters:

Number of moles  = 0.4moles

Unknown:

Mass of the compound  = ?

Solution:

To solve this problem;

   Mass  = number of moles x molar mass

 Molar mass of NaBH₄   = 23 + 10.8 + 4(1)  = 37.8g/mol

 Mass of the compound  = 0.4 x 37.8  = 15.12g

Answer:

The answer is 15.12 g but if you are taking this test on ck12 make sure you round it to 15 like it says on the directions :) good luck

Answer:

Electrolytic cleaning is a method of removing soil, scale or corrosion products from a metal surface by subjecting it as an electrode to an electric current in an electrolytic bath. It is a form of electroplating that can be applied to all electric conductive materials.

Answer:

Compound 1- molecular solid

Compound 2- ionic solid

Compound 3- ionic solid

Explanation:

An ionic solid has a high melting point and does not conduct electricity in solid state. Rather, it's solution or melt is a good electrical conductor.

On the other hand, a molecular solid is a poor conductor of electricity. It has a low melting point and does not easily dissolve in water.

Answer:

NADH is formed

Explanation:

Answer:

Explanation:

The chemical formula for Sulfuric acid​ is H₂SO₄

Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of [tex]NaClO_3[/tex].

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]   

[tex]\text{Moles of} NaClO_3=\frac{12g}{106.5g/mol}=0.113moles[/tex]

The balanced chemical equation for decomposition of [tex]NaClO_3[/tex] is:

[tex]2NaClO_3\rightarrow 2NaCl+3O_2[/tex]  

According to stoichiometry :

2 moles of [tex]NaClO_3[/tex] give = 2 moles of [tex]NaCl[/tex]

Thus 0.113 moles of [tex]NaClO_3[/tex] give =[tex]\frac{2}{2}\times 0.113=0.113moles[/tex]  of [tex]NaCl[/tex]

Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of [tex]NaClO_3[/tex].

[tex]2.11x10^{22}atoms[/tex]

Explanation:

Hello!

In this case, considering the Avogadro's number, which relates the number of particles and one mole, we can infer that 1 mole of any element contains 6.022x10²³ atoms as shown below:

[tex]\frac{6.022x10^{23}atoms}{1mol}[/tex]

Thus, we compute the number of atoms in 0.035 moles as shown below:

[tex]atoms=0.035mol*\frac{6.022x10^{23}atoms}{1mol} \\\\atoms=2.11x10^{22}atoms[/tex]

Answer:

In this practical, students explore the formation of esters through the ability of different alcohols to react with organic acids. Together, the class can quickly produce a range of esters on a test tube scale, with a variety of interesting smells to sample and compare

The pictured ester can be prepared by the combination of ethanol and propionic Acid. The name of the ester in the picture will be ethyl propanoate.

Chemicals called esters are created when an oxoacid reacts with a hydroxyl molecule, such as alcohol or phenol. Esters are widely used. The fatty acid esters of glycerol are the majority of naturally occurring fats and oils.

When an ester reacts with either an amine or alcohol, the reaction is referred to as aminolysis; when an ester reacts with water, it is referred to as hydrolysis of ester. Esters are primarily utilized in flavorings and fragrances, but they can also be employed as solvents in the chemical industry.

Therefore, ethanol and propionic acid can be combined to create the ester shown.

Answer:

The Industrial Revolution was a period of great industrialization that began in the late 18th century in Britain, leading to massive population growth and agricultural innovations, which laid the foundation for increased productivity, both with increased labor and a larger market for the products. There was a revolution in the production methods of the textile industry, especially with the advent of the steam engine and urban development, the influx of people from the countryside to the cities meant that there was an abundance of labor, which laid the foundation for the industrial cities of the nineteenth century.  The steam engine was also used in the new generation of transport, in locomotives and steamships. With the advent of steel as a building material along with a series of new discoveries in communication technology in the second half of the 19th century, the tone was set for the continued technological development of the 20th century.
